First off, let me say this is FICTION. It is free to be over dramatic, sappy, and unrealistic. That is part of what makes fiction so enjoyable-- it's not something we see everyday. Some of the characters do cry in situations a lot of people, especially males, probably wouldn't actually cry about in real life, which you see in the first episode. And since I'm not a guy or a gay guy, I guess I can't really have an opinion on how boyish or girly the guys in this are, but generally I don't think they're too feminine, and I don't think it even matters either way. There ARE quite a few gay characters in this that are all connected in some way, which I can see is unrealistic, but again, it's fiction, and I want to add that a lot of them do go through trouble accepting their feelings toward another guy or acting embarrassed when they're saying something romantic. But, this doesn't focus much on them accepting their sexuality. It doesn't totally ignore it like everybody's gay and it's super acceptable, either. Anyway...
This anime makes me so happy when I watch it. It may not be genius writing or anything, but I don't care. It's sweet, adorable, hilarious, and fun to watch. If the borderline harassment doesn't bother you too much (a certain character is pretty inappropriate with his touching, especially at first, though they go into that later and explain how they both actually feel about it. Also he's my absolute favorite character despite him acting like that) you might grow to adore the characters as much as I do.
If you're wondering if this is a soft shonen ai or a yaoi, it's definitely a shonen ai with some short sex scenes that don't actually show anything. And it may not have a deeper plot to it, but that's because the story is just about their day to day lives and watching the characters and their relationships grow bit by bit. If you love slice of life, romance, and comedy, this anime is really great.
